There are not any current plans to release 0.2 to the public for free.
butyou then could make a 0.3 which can also help the patreon not be bored of the game
When I have a plan for 0.3 I'll look at a public release schedule for 0.2. Patrons are always 1-2 versions ahead of the public release so it depends on demand from them (and time in the production schedule) as to when these things happen.
